A demolition system includes a frame, a plurality of outriggers, a demolition apparatus, and a water reservoir. The frame includes a frame base, a plurality of support members coupled to the frame base, a platform coupled to the plurality of support members, and one or more lifting ears extending from the platform. The plurality of outriggers are coupled to the frame base. The demolition apparatus is coupled to and supported by the frame base. The demolition apparatus includes a main body rotatably coupled to the frame base, an arm extending from the main body between two of the plurality of support members, one or more gripping members coupled to the arm, and a motor configured to selectively rotate the main body relative to the frame base. The water reservoir is coupled to and supported by the platform of the frame. Additionally, the water reservoir provides water to the demolition apparatus.

A demolition machine includes a deck having a front edge, a rear edge, a left side, and a right side, with the deck defining a central axis along a direction extending from the rear edge to the front edge and equally spaced from the left side and the right side of the deck, a drive assembly secured to the deck, with the drive assembly rotatable relative to the deck, an engine received by the deck and positioned at one of the left side and right side of the deck, an energy reservoir and hydraulic reservoir each received by the deck and positioned on an opposite side of the deck from the engine, and a boom assembly secured to a boom support structure of the deck. The boom assembly is moveable relative to the deck, with the boom support structure positioned on the central axis.

A demolishing method utilizes an aggregate stack demolishing scaffold apparatus mounted to an upper part of an aggregate stack including four smoke funnels arranged adjacent to each other. An uneven scaffold including one plate-shaped upper scaffold portion is placed on an upper end of each smoke funnel. A lower scaffold portion is coupled to the upper scaffold portion and located in lower positions in the smoke funnels with the upper scaffold portion being placed on the upper ends of the smoke funnels. A chain block suspends and supports the uneven scaffold from and on an inner wall of each smoke funnel, and adjusts a suspending height. With this configuration, the upper scaffold portion is located on the upper ends of the smoke funnels, and thus there is no possibility of contact between the scaffolds in the smoke funnels causing a worker to lose his balance, thereby improving safety.

A method for, in particular completely or partially, disassembling a tower of a wind power plant, comprising the following steps: selecting suitable disassembly measures as a function of the tower location and the tower characteristics; preparing the disassembly, in particular of the tower and optionally the surroundings; carrying out the disassembly; and transporting the disassembled tower away.

To provide a method of toppling a tower structure more safely, simply and quickly than in the conventional manner. In a method of toppling a tower structure that is fixedly supported on a base 20 to demolish the tower structure 10, the method includes a base dividing step of dividing the base 20 into an upper base 22 and a lower base 26, by cutting the base 20 in a substantially horizontal direction, an upper base dividing step of dividing the upper base 22 into a support base portion 23 and a separated base portion 24 by cutting the upper base 22, in a longitudinal direction, from above to a substantially horizontal surface 20a, a removing step of removing the separated base portion 24, and a toppling step of toppling the tower structure 10 together with the support base portion 23 using, as a tumble axis 23a, a lower edge of a longitudinally cut surface 22a of the support base portion 23, in which the tumble axis 23a is located on a toppling direction side of the tower structure with respect to a center of gravity C. Thus, since the tumble axis 23a of the robust base serves as a tumble fulcrum by itself, there is no possibility that breakage of the base is caused even by the concentration of a buckling load, and the tower structure can be toppled in an intended direction.

A chimney liner removal apparatus including a main chassis, a first telescoping front arm, a second telescoping front arm, a rear telescoping arm, a movable mass and an extendible excavator. The first telescoping front arm is fixedly connected to the main chassis and includes a first hollow member and a first extendible member within the first hollow member. The second telescoping front arm is fixedly connected to the main chassis and includes a second hollow member and a second extendible member within the second hollow member. The rear telescoping arm is fixedly connected to the main chassis and includes a third hollow member and a third extendible member within the third hollow member. The movable balance mass is arranged on the third hollow member. The extendible excavator assembly is pivotally connected to the main chassis opposite the rear telescoping arm.

Disclosed is a system and method for the demolition of vertical concrete structures. A moveable concrete cutting vehicle includes a carriage adapted to move along the top surface of the vertical concrete structure that is to be demolished. The carriage carries a cutting assembly that is moveable in at least two directions, such as a vertical direction and a slightly downwardly angled circumferential direction, which cutting assembly is positioned to make cuts through the entire width of the concrete wall of the vertical concrete structure. After a series of cuts have been performed, the carriage may be moved along the top, horizontal rim of the vertical concrete structure, and separable concrete blocks that have been formed in the previously processed region may be tipped off of the remaining vertical concrete structure to fall to the ground. Such process may continue with the carriage carrying the concrete cutting vehicle progressively downward and around the vertical concrete structure, allowing small, block-shaped sections of the concrete structure to be tipped into the concrete structure until the entire concrete structure has been demolished.
